Boa tarde galera, estou programando um algoritmo para calculo de check sum, porém o calculo não está sendo compilado corretamente, por favor deem uma olhada para ver aonde estou errando, já estou quebrando a cabeça uma semana nesse trem kkk Segue também o fluxograma para o calculo.

Boa tarde galera, estou desenvolvendo um programa para conversar com um equipamento atraves da serial, porém estou com um problema no meu codigo, acredito que na configuração dos bits. Desenvolvi o codigo e no simulador ele esta enviando os dados corretos, porém, quando faço o teste com um CI, não consigo enviar os dados pela serial, o software hercules (software para testes de comunicação) não o recebe. Anexei o codigo, se puderem, me ajudem por favor. PIC 18f4550, cristal de 20MHZ
